Ok. So first of all, I am making this game for my friend, but we wanna do it together. MPStudio has been out for a long time, and it seems like it doesn't work unless you port forward. I used the Old MPStudio that was in the settings and I tried putting in my IPv4 Address, and it didn't work. Please help me learn how to use MPStudio!

Im pretty sure MPStudio is multi player studio so... You can use hamachi and create a network get your friend to join then he can look at your ipv4 address on your hamachi and connect to your game.
